ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 267 



Protozoa. 



Latent Life in Protozoa.* — F. Noc reports on some tubes containing 

 a little water and various Protozoa, which were hermetically sealed in 

 1908 and recently opened. There was no trace of anything but encysted 

 Arncebse, some of which revived after ten days or more. This proves 

 survival for six years. A minute Flagellate, Oikomonas termo, was got 

 from some rough Tonkin paper after desiccation for five years. 



North Sea Foraminifera. f — Edward Heron- Allen and Arthur 

 Earland report on Foraminifera dredged by the ' Huxley ' from the 

 North Sea. The dredgings examined consisted of loose sand with a con- 

 siderable quantity of mud. The list of Foraminifera contains no fewer 

 than 133 species and varieties, many of which have not been recorded 

 previously from the areas in question. But it must not be concluded 

 from the extended list that the material was rich in Foraminifera. Except 

 in the case of a few dominant species the number of actual specimens 

 was very small. A noticeable feature from the southern part of the 

 area was the frequency of fossil forms. 



Clare Island Foraminifera. J — Edward Heron- Allen and Arthur 

 Earland have given a beautifully illustrated account of the Foraminifera 

 of the Clare Island area. They found no fewer than 299 species, of 

 which 14 are new (in the genera Planispiri?ia, Bathysiphon, Bolivina, 

 Lagena, Lingulina, Frondicularia, Discorbina, and Rotalia). They 

 report 32 species new to the British Isles, and 20 of which only a single 

 previous British record exists. Of the specimens new to the British 

 Isles, 7 are recorded for the first time as living Foraminifera, having 

 been already recorded as British fossils, for the most part post-Pliocene 

 or sub-recent. The paper is a model of fine workmanship. 



Pacific Ocean Species of Lagena.§ — Henry Sidebottom reports 

 on a collection of species of Lagena from the south-west Pacific Ocean. 

 They were arranged on slides by the late Mr. Thornhill, and include 

 over 12,000 specimens. Numerous species are recorded, including a 

 few new forms. 



Degeneration in a Parasitic Infusorian.||— Bernard Collin de- 

 scribes degenerative forms of Chromidina elegans from the kidneys of 

 Sepia elegans. There are normal forms which fix themselves temporarily 

 by their cilia to the outside of the fungiform bodies or swim freely in 

 the urinary fluid, and there are the degenerate forms which traverse 

 the epithelium of the follicles and are imprisoned in the vascular 

 lacunae within. They increase greatly in size ; the nucleus shows
